Abstract
An instruction simulation device and a method thereof are provided. The instruction simulation device includes a processor. The processor includes an instruction decoder which generates format information of a ready-for-execution instruction. The processor determines whether the ready-for-execution instruction currently executed by the processor is a compatible instruction or an extended instruction based on the format information of the ready-for-execution instruction. If the ready-for-execution instruction is an extended instruction under the new instruction set or the extended instruction set, the processor converts the ready-for-execution instruction into a simulation program corresponding to the extended instruction, and simulates an execution result of the ready-for-execution instruction by executing the simulation program. The simulation program is composed of at least one compatible instructions of the processor. If the ready-for-execution instruction is a compatible instruction, the processor executes the ready-for-execution instruction.
